This video demonstrates an advanced gunsmithing technique for relocating a cam hole on a 1973 Shovelhead Harley-Davidson alternator motor. The process involves welding the original hole, precisely locating the new position using a milling machine with a digital readout and dial indicator, and then carefully machining the new hole to accept a cam bearing. The instructor emphasizes the importance of using the right equipment for accuracy and efficiency.

Dragonman demonstrates a specialized process for repairing and relocating Harley-Davidson cam bearing holes. This involves using custom fixtures and a dial indicator to precisely locate the center of the damaged hole, followed by drilling and milling to create a new bore for an interference press-fit bearing. The guide also covers the correct method for installing the new bearing using a specialized punch.

This video details the use of a rare 1973 U.S.G.I. firing pin protrusion gauge for the M16 rifle. It explains the gauge's components, calibration process using a dial indicator and set ring gauge, and its application on an M16 bolt carrier group. The presenter demonstrates how to check firing pin protrusion against specified tolerances, comparing it to other methods and highlighting its historical significance.

This guide details how to use the Hornady Concentricity Gauge to measure and correct bullet run-out in loaded ammunition. Instruction from an expert highlights how proper alignment ensures consistent rifling engagement, leading to improved accuracy. The process involves using the gauge's dial indicator and adjustable ram to achieve straighter bullets, with noted variations in performance depending on the rifle.

This guide details the advanced gunsmithing process of relocating a cam hole on Harley Davidson engine cases, specifically for models from 1972-1999. It involves precise welding, specialized fixtures, and custom-ground end mills to achieve a perfect press fit for the cam bearing. The technique emphasizes accuracy using dial indicators and milling machines to ensure the new hole is perfectly centered and perpendicular to the case.

This guide details how to repair a bent ejector rod on Smith & Wesson revolvers, a common issue affecting cylinder operation. Expert gunsmith Larry Potterfield demonstrates using precision tools like a dial indicator and lathe for accurate straightening. The process involves diagnosing the bend, careful disassembly, straightening the rod, and reassembly with functional testing.
